Answer» <html><body><p></p>Solution :Elasticity of steel is more than that of coppper. It means that the elastic limit of limit is <a href="https://interviewquestions.tuteehub.com/tag/greater-476627" style="font-weight:bold;" target="_blank" title="Click to know more about GREATER">GREATER</a>. Let us consider two springs of the same size, one of steel and another of copper.An equal <a href="https://interviewquestions.tuteehub.com/tag/tensile-1241684" style="font-weight:bold;" target="_blank" title="Click to know more about TENSILE">TENSILE</a> force is applied on both springs. On slowly increasing the magnitude of the applied force on the two springs it seen that,at a certain stage the steel spring still behaves like an elastic body but the copper spring undergoes a permanent <a href="https://interviewquestions.tuteehub.com/tag/deformation-947276" style="font-weight:bold;" target="_blank" title="Click to know more about DEFORMATION">DEFORMATION</a> .
